SPECIFICATION forming part of Letters Patent No. 654,537, dated July 24,1900. Application filed May 17, 1900. Serial No. 17,001. (No model.)

To a/ZZ whom t may concern.-

Beit known that I, HARRY GREENWOOD, a citizen of the UnitedStates,residing at Barnesborough, in the county of Cambria and State ofPennsylvania, have invented certain new and useful Improvements inLamp-Burners;

and I do declare the following to be a full,

whereby the claw-bar will be retained inl proper position with respectto the wick-tube and wick therein and provision made forholdinglamp-chimneys of different sizes.

In the accompanying drawings, Figure lis a perspective view of myimproved lampburner. Fig. 2 is a vertical sectional view. Fig. 3 is adetail perspective View of the wicktube and its attaching-plate removedfrom the burner, and Fig. 4 is a similar view of the claw-bar.

In the drawings the same reference characters indicate the same parts ofthe invention.

Referring to said drawings, l denotes a claw-bar which extends through aportion of the body of the burner and is formed with a head 2, providedwith teeth 3,which are adapted to project through alongitudinally-disposed opening e in the wick-tube and engage the wick.This wick-tube is soldered or other-y wise secured to a circularandpreferably conV vex plate 5', which is in turn soldered or other wisesecured to the collar 6 of lthe burner. The side walls of thelongitudinally-disposed opening through which the head of the claw-barprojects into engagement with the wick are provided with parallelverticallydisposed guide-flanges 5, preferably formed integral with thetubethat is to say, stamped out.

of the same material-and angles to the tube and project at right preventthe displacement of the claw-bar due to the lateral shifting of thelever in the careless manipulation of the same. Ooiled around thisclaw-bar and confined between the burner and the head of the clawbar isa spring '7, the energy 0f which is exerted to force the teeth into thewick and to hold the wick in its adjusted position.

In operation if it be desired to elevate the wick the claw-bar isgrasped and pulled outward. Thence the claw teeth are swung downward byelevating the upper end of the bar and engage with the wick. Then bydepressing the bar the wick is elevated the dis'- tance of movement ofthe claw-bar. A reverse movement of the bar will lower the Wick.

When adjusted, it will be noticed that owing to the tension of thespring the wick will be held firmly in place, so thatthere will be noliability of its being jarred down if the lamp is suddenly placed upon atable or if the burner be used for a lantern when the lantern is vioLlently swung in giving signals.

The guide-flanges provide against the accidental shifting of theclaw-head from engagement with the wick, due to careless manipulation ofthe claw-bar.

It will of course be understood that various lchanges in the form,proportiomand the minor details of construction may be resorted towithout departing from the principle or sacrificing any of theadvantages of this invention.

Having thus fully described my invention, what is claimed, and desiredto be secured by Letters Patent, is-

The combination with a lamp-burner provided with an opening in itsvertical wall and with a longitudinal slot in its wick-tube, the sidesof said slot being bounded by parallel vertical projecting guide-flangeswhich eX- tend from said wick-tube at angles thereto, of a claw-barextending through said opening and providedv with a shouldered head,said head being provided with teeth in position to engage the wickthrough the slot in the tube, and a coil-spring around the bar, one endof which engages with the Wall of the burner and the other end engageswith the shoulder of the head, substantially as and for the purpose setforth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witn nesses.
